sciencehabit writes "Researchers say they have discovered the fossils of 3.4-billion-year-old cells in between the cemented sand grains of an ancient beach in Western Australia, possibly the oldest fossils ever found (abstract). Chemical analyses of the minerals near the cells suggest the microorganisms depended on sulfur for fuel. Such a beach might have been life's first breeding ground, one author says."

Hugh Pickens writes "According to an article by Tony Bradley, news is spreading quickly online that HP is going to clear out its vast TouchPad inventory by dropping the price to an offer you can't refuse. Rumor has it that beginning Saturday the 16Gb TouchPad will be $99, and the 32Gb TouchPad will be a measly $149. 'It is actually a fairly capable tablet. It's just not an iPad 2,' writes Bradley. 'For $500 it was a joke. For $300 it was still a shady deal. For $99 it's a steal.' HP has learned the hard way, and quickly pulled the plug on its tablet, proving that HP never had a solid tablet or mobile strategy and that it was really just looking for an excuse to get out. 'The reality is that my Best Buy is swimming in unsold HP TouchPad inventory,' adds Bradley. 'I went out tonight and picked mine up at the regular $400 price to beat the rush. Situations like this are why they invented price matching. I can just go back with my receipt once the fire sale starts and get the price adjusted and the difference refunded.'"

CWmike writes "With HP spinning off its PC business, rivals will be looking for a way to get a bigger piece of the hardware pie. HP's PC unit news, among other industry-rattling announcements, including pulling out of the tablet market and shuttering webOS, rocked the hardware industry since HP is by far the dominant maker in the world. So while HP decides what to do, rivals should be plotting their next move, say industry analysts. Who could benefit the most from any change-up in PC sales? The obvious suspects: Dell, which passed Acer in the second quarter of this year; and Acer is looking to make up some lost ground and could see HP's shake up as an opportunity. And don't forget Lenovo, which holds the third-largest market share. Despite the general downshift for PCs, Lenovo is riding some great momentum right now, reports Gartner. In the second quarter of 2011, the company saw 22.5% growth in its PC shipments." A related article ponders the fate of webOS, looking at a number of potential buyers as well as the unlikely possibility that HP will open source it.

A number of readers submitted rumors about some announcements HP was set to make today. Now, the announcements have actually happened, and the news looks grim. For starters, they are exiting the tablet and phone market and repositioning webOS for use in appliances and vehicles. While confirming they are in talks to acquire Autonomy, they also announced they are considering exiting the PC hardware business entirely in order to focus on their software business.

An anonymous reader writes "The Netherlands is testing a new car use tax system that will tax drivers based upon how much they drive rather than just taxing the vehicle itself. The trials utilize a little box outfitted with GPS, wireless internet, and a complex rating system that tracks a car's environmental impact, its distance driven, its route, and what time it is driven as a fairer way to assess the impact of the vehicle and hopefully dissuade people from driving. The proposal will be introduced slowly as a replacement for the current car and gas tax, however it is most certainly controversial and will be a real test of how far environmentally savvy Dutch citizens will be willing to go to reduce the impact of the car."

sciencehabit writes "Researchers have developed ultrathin electronics that can be placed on the skin as easily as a temporary tattoo (abstract). The scientists hope the new devices will pave the way for sensors that monitor heart and brain activity without bulky equipment, or perhaps computers that operate via the subtlest voice commands or body movement. The devices can even be hidden under actual temporary tattoos to keep the electronics concealed, giving them potential applications for espionage."

sciencehabit writes "Cygnus X-1 bears its name because it was the first source of x-rays found in the constellation Cygnus. In 1971, astronomers discovered that the x-rays came from the direction of a bright blue star whirling around a mysterious dark object. They speculated that the x-rays were resulting from material being torn away from the bright star and falling onto the dark object, perhaps a black hole. This year, astronomers established that Cygnus X-1 does indeed harbor a black hole, a dead star whose great gravity lets nothing, not even light, escape. Now that result has inspired a forecast for the system's future: The black hole will swallow even more mass from an unfortunate star circling it, then likely dash away on its own when its companion explodes."

oxide7 writes with this selection from IBT: "Hewlett Packard reduced the price of its TouchPad tablet computer again, highlighting the uphill battle manufacturers will need to overcome as they go head-to-head against the dominant Apple iPad line of tablets. Much of a tablet's success is based on the ecosystem of apps that is available to the end-user. HP is far behind Apple or even the No.2 tablet platform, Google's Android."

sciencehabit writes "A small number of people in the world don't have fingerprints. The condition is known as adermatoglyphia, and one scientist has dubbed it the 'immigration delay disease' because sufferers have such a hard time entering foreign countries. In addition to smooth fingertips, they also produce less hand sweat than the average person. Now researchers have identified the genetic mutation behind the condition (abstract)."

alphadogg writes "It's the last Friday in July. Have you hugged your system administrators today? Bought a cake? Picked up the tab for lunch? There's still time to show your thanks for the unsung heroes who keep corporate desktops, servers and networks running. Today is System Administrator Appreciation Day, an annual event thought up by IT pro Ted Kekatos. A company picnic and an old HP advertisement sparked the idea for the first SysAdmin Day, now in its 12th year."

An anonymous reader writes "About six months ago, however, I began to wonder about how the other mobile products had grown. When the HTC HD7 crossed my path a little while ago, I decided to abandon my Nexus S and live among the Windows Phone folks for awhile. The experience was fun, but I eventually went back to my Nexus S. About a month later, I was presented with the opportunity to repeat the experiment, only this time with a Palm Pre Plus. With the HP Touchpad on its way, I wanted to get a feel for how WebOS worked, explore the differences, and take a look into the community that was still loyal to WebOS."

sciencehabit writes "A new study suggests that by twisting laser light, scientists could pack enough information into interplanetary beams to speed up extraterrestrial communications to the multi-gigabit level. The pulses would be passed through a hologram or multimode optical fiber, which twists the light. On the other side, a telescope would focus the light and a second hologram, or fiber would decode the signal. That could allow much more data-rich communication between, say, Earth and probes on Mars, the researchers say. Closer to home, the approach could provide Internet links of 100 gigabits per second."

sciencehabit writes "It started with a single monkey coming down with pneumonia at the California National Primate Research Center in Davis. Within weeks, 19 monkeys were dead and three humans were sick. Now, a new report confirms that the Davis outbreak was the first known case of an adenovirus jumping from monkeys to humans. The upside: the virus may one day be harnessed as a tool for gene therapy."

sciencehabit writes with this excerpt from Science: "While exploring Australia's Great Barrier Reef, professional diver Scott Gardner heard an odd cracking sound and swam over to investigate. What he found was a footlong blackspot tuskfish holding a clam in its mouth and whacking it against a rock. Soon the shell gave way, and the fish gobbled up the bivalve, spat out the shell fragments, and swam off. Fortunately, Gardner had a camera handy and snapped what seem to be the first photographs of a wild fish using a tool." (Not everyone agrees that this constitutes tool use, says the article, in part because the "tool" isn't something that the fish can actually manipulate.)

sciencehabit writes "The scratchy, 12-second audio clip of a woman reciting the first verse of Twinkle, Twinkle, Little Star doesn't sound like much. But the faint, 123-year-old recording—etched into a warped metal cylinder and brought back to life after decades of silence by a three-dimensional (3D) optical scanning technique—appears to belong to the first record intended for sale to the public. Made for a talking doll briefly sold by phonograph inventor Thomas Edison, the early record is the oldest known American recording of a woman's voice and may be the oldest known record produced at Edison's laboratory in West Orange, New Jersey."

Fudge Factor 3000 writes "HP released their much trumpeted enterprise tablet, TouchPad, last week. This device was also the first to showcase WebOS in a tablet. The tablet received several harsh reviews, though some stated that the OS showed potential. Most of the criticism surrounded the sluggish software and the lack of apps. As reported by CNET, WebOS chief Jon Rubenstein rallies his troops by comparing the WebOS tablet's debut to that of Mac OS X, which also struggled early on. However, it is not entirely clear if the comparison is appropriate, since WebOS has existed since 2009, and OS X had the ability to run most classic OS 9 apps during the transition period. Nevertheless, one can certainly argue that the situation is similar in spirit." Another reader tips a related article which suggests that — for better or worse — Apple has succeeded in defining what a tablet should be, making it difficult for competitors to get a foothold in the market.

sciencehabit writes "In a new study, a team found that injecting mice with tiny magnets and cranking up the heat eliminated tumors from the animals' bodies with no apparent side effects. The nanoparticles heat up when a magnetic field is applied, and because they are only injected into tumors, only cancerous cells get fried. Researchers hope the technique, known as magnetic hyperthermia, could be used in cancer patients, obviating the need for chemotherapy and radiation."

sciencehabit writes "Patients suffering from the agony of cluster headaches will take anything to dull the pain, even LSD, it turns out. Results from a pilot study reveal that six patients treated with 2-bromo-LSD, a nonhallucinogenic analog of LSD, showed a significant reduction in cluster headaches per day; some were free of the attacks for weeks or months. And some of these patients are still reporting significant relief more than a year after they were treated with the compound." I'm told, by people with reason to know, that the hallucinogenic variety has the same effect on cluster headaches.

Esther Schindler writes "Every mobile device you own has its own power supply and its own proprietary plug. There oughta be a better way, says Alfred Poor. Fortunately, he reports, the IEEE is coming to the rescue. "Their Universal Power Adapter for Mobile Devices (UPAMD) Working Group is developing a new standard that will not just address the needs of laptops and tablets, but will be intended to work with just about any electronics device that required between 10 and 240 watts of power," Poor writes. It's about darned time." If there's one thing I wish for all laptop power supplies, it's that they would license from Apple (or work around, patent-wise) the magnet attachment system that makes cable-tripping far less dangerous to man or beast, compared to a few years ago.

sciencehabit writes "Imagine life on an Earth-like moon, one so close to its gas giant host that its landscape is bathed in a dusklike planetary glow. Such places are not only possible but also probable, according to a new study, which finds that as many as 5% of gas giant planets orbiting their stars at Earth-like distances may harbor habitable 'exomoons.' According to simulations, alien gas giants (like our Jupiter and Saturn) could pull in earth-like planets from the interior of their young solar systems. Though many of these planets would crash into the gas giants or later be flung into space, some would evolve stable orbits and stable climates, eventually setting the stage for life."
